APPARATUS FOR SWEEPING STREETS AND RMOVING DIRT THEREFROM.

SPECIFICATION forming part of Letters Patent No. 349,816, dated September 28, 1886.

Application filed May 28, 1885. Serial No. 166,913. (No model.) I

To all whom it may concern.-

Be it known that I, CHARLEs F. W. SEIDEL, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Apparatus for Sweeping Streets and Removing Dirt Therefrom, of which the following is a specification.

My invention relates to that class of streetsweeping attachments which comprise aframework supported by an axle and pair of wheels, an endless carrier having an upward travel, and a rotary brush for delivering dirt upon the carrier, the frame-work of the apparatus being furnished with means whereby it kmay be readily connected with a dirt-cart so as to form an attachment thereto.

The invention consists in a novel combination of parts in an apparatus of the kind above described, as particularly hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side View of the apparatus, one of the sup porting-wheels thereof being removed, and also showing in section an apron or shield covering the apparatus and a portion of the dirt-cart represented in dotted outline. Fig. 2 represents a plan of the apparatus, the apron or shield which forms anexterior covering therefor being removed to illustrate clearly the parts beneath; and Fig. 3 is a plan of a part .of the frame and one of the hooks.

Similar letters of reference designate corresponding parts in all the gures.

A designates a portion of the cart body or box, and A one of the wheels thereof.

My improved apparatus comprises two` side frames, B, which may be made of cast or wrought iron, an axle, C, on which these side frames are supported, and wheels C', which may be of any suitable construction, and are fast upon the axle. These wheels may have teeth or ribs a upon their peripheries, as represented in Fig. 2, so that their rotation will be insured as they vmove over the ground, and as the apparatusY is drawn along the wheels and the axle rotate in unison.

In the lower portions of the side frames, B, is journaled adrum or roller, D, and in the upper portion thereof is j ournaled a second drum or roller, D. Around these two drums or rollers passes anapron, belt, or endless' carrier, Ewhichv may be made of canvas, sheet metal, or other material, and which has secured upon its face transverse lags or shelflike projections b, extending from side to side 5 5 thereof. The side frames, B, also have portions which extend forward over the cart-body A, and have journaled in their extreme forward portions a third drum or roller, D2, around which the belt or carrier E is passed in its 6o travels.

Below audslightly rearward of the drum or roller D is arranged another drum or roller, D3, around which the return portion of the belt or carrier passes, .and which should be 65 notched or grooved longitudinally upon its surface to accommodate the lags or shelf-like projections 'b of the belt or carrier.

Upon the journal or shaft ofthe drum or. roller D is placed a chain-driving wheel, c, 7o which may have a polygonal or toothed periphery, and fast upon the axle C is another chain-driving wheel,` c. An endless drivingchain, c2, passes around the wheels c e' and transmits rotary motion from the axle C to 75 the upper apron drum or roller D', which, in turning, imparts a progressive motion in one direction to the apron or carrier E, moving it in the direction indicated by the arrows in Fig. 1.

From the above descriptionit will be understood that the arrangement of the drums or rollers D D2 Ds is such that the dirt and refuse which is carried upward by the upwardlymoving operation of the belt or carrier is ear- 8 5 ried forward over the cart-box A, and by the passage of the belt or carrier around the drum or roller D2 is deposited in the cart, and by the roller D3 the returning portion of the belt or. carrier is caused to move rearward nearly 9o horizontal until it clears the back of the cartbox and then moves downward to the drum or roller D.

Upon the shaft or axle which supports the lower drum 'lor roller, D, is loosely pivoted a 9 5 guard or conductor, d, which rests upon the ground and has a'curved upper face. This guard or conductor has its facecontinuous throughout the width of the apparatus, and has upwardly projecting arms which are roo loosely pivoted on the shaft of the roller D, and are constructed to enable the apron or carrier E to pass between them and clear the upper edge of the guard or conductor.

Upon the driving-axle C are loosely pivoted at 4opposite sides of the apparatus levers or arms F, which form at their outer ends bearings for the brush G, extending across the apparatus and free to rotate in the bearings. This brush may be of wire, rattan, or other suitable material, and in construction it may be similar to the brushes of street-sweepers heretofore used.

At one side of the apparatus and upon the drivingaxle C is secured fast a gear-wheel, e, and in one of the levers or arms F is iixed a stud, f, on which turns freely a gear-pinion,e, which gears with and receives motion from the gear-wheel c.

Secured fast to the pinion e, so as to rotate in unison therewith, is a'chainwheel, e, and on the brush-shaft is a second chain-wheel, e, and the chain-wheel c and brush G are continuously rotated in the direction of the arrow in Fig. l by aehain e driving from the wheel c2 onto the wheel e3. The rotation of the brush in the direction of the arrow, Fig. 1, picks up the dirt and throws it rearward and against the guard or conductor d, and by said guard or conductor, the dirt is directed upward upon the belt or carrier E, and is thereon retained by the lags or shelf -like projections I, and prevented from sliding off as the carrier moves upward.

To raise the brush temporarily from the ground, Ihave shown rods g as connected with the front ends of the arms or levers F. These rods are connected at their upper ends by a crossrod, with which is connected alever, H, which is fulcrumed at z/ to one of or between the side frames, B, and which, when depressed by the driver, will lift the brush free from the ground and hold it temporarilyin an elevated position.

In order to prevent the dust and dirt from being blown or iiying away from the apparatus while in operation,I have represented an apron or shield, I, which may be carried over rods or supports i, attached to the main frame, and which may be drawn down at the sides and attached to the side frames, B.

I have in Fig. l shown the side frame, B, as having buttons o for securing the apron, shield, or hood to it. The lower end of the apron is connected with arms I, which are loosely fulcrumed upon the shaft of the lower drum or roller, D, and to these arms are applied coiled springs i2, 'which exert aconstant tendency to tighten the apron upon its supports fi, consequently the apron will not interfere with the raising of the brush G, and when the brush returns to its normal position the apron will automatically tighten upon the supports i andwill serve its purpose of preventing the dirt from flying away.

At the lower part of the apron or hood I is an opening, through which the brush works. At the upper end of the apparatus this apron may be carried downward and attached tothe cart-box, and in order to prevent the dirt from being blown away as it is delivered into the cart side plates, I2, may be arranged as shown in dotted lines, Fig. 1, so as to cover the sides of the upper part of the apparatus. 2 I have only shown the brush shaft orbody, in order to show the guard el.

For'attachi ng the apparatus to the cart-body A, I have here represented hooks J, one only of which is shown, and which are pivoted to the side frames, B, at j. These hooks engage with projections a* on the cart-body and hold the apparatus to the body while in operation. By means of stop-pins a? the hooks will be prevented from falling below the position in which they. will engage with the projections dit, and their front ends or noses are inclined so that when the apparatus is pulled up against the back of the cart-body the hooks J willrise over the projections a* and engage automatically therewith. I have also represented buffers or bumpers s as provided upon the main frames B of the apparatus, and which will prevent any shock by reason of the apparatus striking against the rear end of the cartbox.

I have shown in Fig. 3 a plan of a part of the frame B, cart A, and the hook J connect- `ing them, all being shown in side elevation in Fig. I.

From the above description it will be understood that my improved apparatus is simple and inexpensive in construction, and may be readily disconnected from one dirteart when the latter is Iilled and connected with an empty cart for use therewith.

.The chain and chain-wheels c2 c cconstitute gearing whereby the carrier drum or roller D is driven from the axle C, and the wheels e c c2 es and chain e4 constitute gearing for driving the brush G from said axle.

Wire ropes or other flexible driving bands or connections may be substituted for the chains and would be the equivalent thereof, suitable pulleys being substituted i'or the chain-wheels.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with the side frames, B, and an axle and wheels for supporting them, of the endless carrier and its supporting and operating drums journaled in said frames, a rotary brush for delivering dirt upon the carrier, rods i', connecting the side frames, and an apron or shield, I, covering the apparatus between the side frames, supported by the rods i, and having at one end a spring-connec tion whereby it is drawn and held taut over the said rods, substantially as herein described.
